Vertical brakes for rail transport equipment

Abstract

The invention discloses a standby vertical brake for a railway transportation device. The standby vertical brake for the railway transportation device is characterized in that one end of an oil cylinder bracket is equipped with an oil cylinder, and while the other end of the oil cylinder bracket is equipped with a pushing rod guide plate which is mounted on a bracket; a chute is formed in the bracket; a spring pushing plate on which a pushing rod is mounted is arranged on an oil cylinder piston rod; a pushing rod is arranged in the pushing rod guide plate by sleeving; a spring is mounted on the spring rod between the spring pushing plate and the pushing rod guide plate; a double-arm clamp type brake consisting of an upper brake arm and a lower brake arm is mounted at the front end of the pushing rod; two ends of a connecting shaft of the upper brake arm and the lower brake arm are arranged in the chute. The standby vertical brake for the railway transportation device has the technical effects that the device is vertically mounted; the oil cylinder, the oil cylinder bracket and other parts can be mounted above a railway transportation device frame without being limited by the lower limited space; the device is simple in structure; the spring and the oil cylinder are mounted by a split manner, so that the dismounting, mounting and maintaining are convenient; when in a non-braking state, a clamp opening of the double-arm clamp type brake can be lifted to be above the railway surface, so that the railway transportation device can smoothly pass through a common turnout.

Description

technical field [0001] The invention relates to a rail transportation equipment brake. Background technique [0002] There are two installation methods for the brakes of rail transportation equipment: horizontal installation and vertical installation. During the braking process of the traditional horizontal structure installation, the braking force cannot fully act on the track, and part of the force acts on the cylinder connected to the brake arm. Sleeves, cylinders or push plates are tilted due to uneven force, which hinders the transmission of braking force, and this installation method is limited by installation conditions, so it can only be installed under the frame of the transport equipment, which increases the Brakes are difficult to install and maintain. Traditional vertically installed brakes use multiple oil cylinders, and the brake arms on the left and right sides are not controlled by one oil cylinder at the same time. In the case of non-braking, the brake blo...

Problems solved by technology

[0002] There are two installation methods for the brakes of rail transportation equipment: horizontal installation and vertical installation. During the braking process of the traditional horizontal structure installation, the braking force cannot fully act on the track, and part of the force acts on the cylinder connected to the brake arm. Sleeves, cylinders or push plates are tilted due to uneven force, which hinders the transmission of braking force, and this installation method is limited by installation conditions, so it can only be installed under the frame of the transport equipment, which increases the Brake installation and maintenance difficulty

Traditional vertically installed brakes use multiple oil cylinders, and the brake arms on the left and right sides are not controlled by one oil cylinder at the same time. In the case of non-braking, the brake block is only in the state of being open and not in contact with the track, and cannot be lifted above the track surface, and the rail transportation equipment cannot pass through the ordinary fork.

At the same time, the disc springs of these two brakes are installed on the piston rod in the oil cylinder, which is not convenient for installation and maintenance.
